Hi, i need run cuberite with a windows x86 pc. But i want use minecraft 1.5.2 client. How i can do it? i can't find any version compatible with protocol 61 (1.5.2).

Hello and welcome to the forum.
I'm afraid you'll have to download the source yourself and compile it. The last commit that supported that version is 439f07cab5b06d9fce691388646fa7f00dd57703
Many features may be missing though.
